Gazelle S1003i Series L2 Manageable Industrial Switch/Serial Device Server Product Overview The Gazelle S1003i Series combines an industrial switch with an optional RS-232/485 serial port.

1 Gazelle S1003i Series L2 Manageable Industrial Switch/Serial Device Server Product Overview The Gazelle S1003i Series combines an industrial switch with an optional RS-232/485 serial port. The switch part is a Layer 2 Din-Rail manageable industrial switch designed to satisfy the requirements of data transmission in areas of smart grid (IEC , IEEE 1613), transportation (EN ), energy and industrial automation. The design enables maximum flexibility among electrical and ST/SC interfaces. It supports 1 FE ST/SC uplinks, and 2 FE downlinks. Network redundancy and reliability are guaranteed with G.8032 ERPS (<50ms switch-over time), and 12/24 VDC, 24/48 VDC or 110/220 VDC/VAC power supply. Highlights 1/0 RS-232/422/485 serial ports Compliant with IEC and IEEE 1613 (power substations) as well as EN (railway applications) Support standardized G.8032 Ethernet ring protection switching with a recovery time less than 50ms VLAN Wide operating temperature range IP40 protection level Rugged Din-Rail design MTBF >35 years Specifications Interface: 1*FE 1x9 SC/ST/SFP optical ports 2*10/100Base-TX RJ45 electrical ports 1* RS-232/485 serial port (Optional) Reset Botton: 1 Dimensions: 105mm(D)*56mm(W)*135mm(H) Weight: 0.7Kg Installation: Din-Rail, wall mountable, rack-mountable(tray installed) Operating temperature: - 40 to 85⁰C Storage temperature: -40 to 85⁰C Humidity: 5% to 95%, non-condensing Power supply (input Voltage): -DC 12/24V (10~36V) - DC 24/48V (20-72V) - AC/DC 220V (AC: V; DC: V) Power consumption: <3W
